Abstract: The invention relates to an infrared (“IR”) thermometer that includes a pistol-grip handle which is operable to receive a high-voltage removable and rechargeable battery pack. In one embodiment, the thermometer includes a main body, a handle portion, a trigger, a display, a control section, an LED flashlight, a plurality of sensors, and a high-voltage removable and rechargeable battery pack. The handle forms an oblique angle with respect to the main body and includes a first recess for receiving the battery pack. The trigger is operable to initiate a temperature measurement, and the display is operable to display, among other things, a measured temperature. The plurality of sensors include, for example, an IR temperature sensor, a thermocouple, a humidity sensor, and an ambient temperature sensor.

Abstract: The invention provides a non-contact voltage detector (“NCVD”) that includes a housing, a power switch, and an LED flashlight. The housing includes an upper portion and a lower portion which are slidably attachable to one another. A voltage sense circuit is positioned within the housing and illuminates a voltage sense indicator when it detects an AC voltage. The power switch is operable to activate the voltage sense circuit and the LED flashlight. The NCVD includes a first set of rails and a second set of rails for slidably attaching the NCVD to a test and measurement device, such as a digital multimeter (“DMM”) or an infrared (“IR”) temperature gun.

Abstract: A system includes a power tool having a motor, a drive mechanism mechanically coupled to the motor, and an output element mechanically coupled to the drive mechanism. The motor is operable to drive the drive mechanism and the output element. The system also includes a non-motorized sensing tool having a printed circuit board and a sensing element electrically coupled to the printed circuit board. The sensing element is operable to detect an external characteristic and output a signal to the circuit board. The circuit board is operable to condition the signal into a human-comprehensible form. The system further includes a rechargeable battery pack removably and independently coupled to the power tool and the non-motorized sensing tool. The battery pack is operable to power the motor to drive the drive mechanism and the output element when connected to the power tool, and is operable to power the circuit board and the sensing element when connected to the non-motorized sensing tool.
